N.Y. Village Law § 11-1114
The board of commissioners shall have authority to determine the manner and conditions under which said supply pipes shall be installed and shall have authority to install and maintain said supply pipes and to adopt such uniform service charges as they deem just for each supply pipe so connected with the mains or distributing pipes and extending to the street or right of way lines, regardless of the location of said water mains or distribution pipe within said streets or rights of way lines and regardless of the soil, rock or other physical conditions within said streets or rights of way lines.
Such uniform service charge as the board may adopt shall be any percentage of the cost up to but not exceeding the average actual cost of installing such supply pipes as before described. Such percentage of the average actual cost of installing such supply pipes as may not be charged shall be borne by the village.
The said board shall have authority to apply such percentage of the average actual cost of installing such supply pipes as the village might pay, to such other supply pipe connection for the same property or properties as in the judgment of the board might be advisable.
The board of water commissioners may cause a notice to be published in the official newspaper of the village and if so published, shall serve on the owners or occupants a printed notice notifying such owners and occupants of any and all property fronting or abutting on any street, right of way or portion thereof, in or upon which any public water main or distributing pipe is about to be laid or is being laid or has been laid by said board, that connection pipes to and from the water mains or distribution pipes in said street, right of way or any portion thereof in front of each separate piece of property and where directed by said board, shall be installed by said board in such manner and under such conditions and at such prices as said board shall prescribe.
The said board shall have authority to assess the actual cost of such connection pipes or such service charge as may be determined and the actual cost of maintaining the same upon the property so connected. Should the owner of said property so connected fail to pay the cost or charge thereof, the said board shall have authority to add such cost or charge to the annual tax on such property and collect the same, therewith, and when so collected, the amount thereof shall be paid into the water fund of the village. Nothing herein contained shall be construed to prevent the financing, in whole or in part, pursuant to the local finance law, of any expense incurred by the village pursuant to this section.
